Very reductionist analysis.

- Electric engines are far more efficient.

Electric engines have a significantly better trust-to-weight ratio.

- Lighter engines on the wing mean lighter overall plane structure

- Batteries can be structural components, not just dead weight, unlike fuel

- Potentially you can use gravity to recharge the battery

You can also do far more with differential thrust and potentially remove the planes tail. Actually you could do that even with normal planes as Chief Scientist at NASA H. Bowers has discovered.

Look at the next generation Tesla battery pack. The batteries are literally what is holding together the car and the resulting weight is not much larger then the structure you would have needed without the battery.

We are not there yet, it takes a complex vertically integrated approach to build such a plane, but it is not impossible. Just like with EV you need to re-engineer and rethink every aspect of the plane.

Your range might still not be as good, but hell of a lot better then 5% and also far, far cheaper to operate.
I'm sure most of you have observed this, but there's a game theory answer to the question of trust:
https://ncase.me/trust/

In practice, distrusting is a matter of worrying about the minority. If you lock anything, you're worried about 1% or 0.1%, maybe less, who will legitimately do something bad. But, the consequences are so heavy that people apply that distrust to everyone.
I don't see how your comment is anything more than FUD.

The leaked information suggests it may have come from Serasa Experian [1], although they deny it, or some third-party that provides services to them. I haven't seen any evidence the government has anything to do with this.

As a passenger, how noisy are the planes?
My grandfather gave me some advice when I was in high school.

He was a radio and communications engineer from the 1950s to 80s. By the time he retired, he'd worked as a program manager with a staff of hundreds. His advice to me, a budding IT enthusiast and likely heading for a career in such, was simple:

"Learn to read and write well. You can't be a good engineer if you can't write well."

It was invaluable advice.
How is this directly related to Bolsonaro? Because it happened in the country he is president of?
Pretty good practical guide, light on formulae, heavy on application.
That is great news! Thank you Florian, Robert, and everybody involved.
You make some good points. A huge part of our experience is the electronically controlled resistance that adds up to 100+ lbs of force. Our high-intensity games and strength content, which differentiates us, requires this and the reason why we opted to build our own rower instead of just an app or working with any rower.
The breakdown of trust in a society is a vicious cycle that seems hard to break.

When a mistrust dynamic sets in, how can it be reversed?
How are signals up to 10Khz generated? I thought the absolute refractory period of a neuronal action potential limits the rate at which they can fire.

Ask HN: What technology has mass adoption ruined?
I'm both mildly annoyed and strongly in favor of them, since they have taught me how incredibly pervasive website tracking of my personal data is. If a website tracks me, I want to know about it, and I want to be reminded to consider whether the website provides value worth giving up my privacy for.

Besides, recent iterations of the cookie banner are (supposed to be) more than just an ok button - they are supposed to provide an opt out mechanism for all non-required tracking. See, for an example, theguardian.com
And it's still on paper, just now with some electronic augmentation that makes vote counting instant and lowers the error rate.

Do you not remember how problematic the purely paper voting systems were? How many errors were made in the voting and the counts and how long it took to get the final results in close elections? Florida 2000 is a famous, widely-known example. The computers are clearly better.
This is much better than chatting face-to-face on Zoom, but team meetings mostly consist of someone sharing their screen while going through JIRA, a doc, deck, or spreadsheet. I'm not convinced screen sharing is as effective in 3D, which eliminates most meetings.
Exactly. I really should have stated this above. You explained it perfectly.
I had that view for the older direct recording systems with no paper trail.

But these seem to record on each machine for a quick count the night of, but then also produce a paper ballot for an audit. Much better. It would be even better if the paper ballot was easy for the voter to quickly validate.

But as long as the machine is really just helping you mark a paper ballot, and it's the paper ballot that is "official" end the end, it seems much safer.
I can just imagine the future: Instead of reading stories of Identity Theft, we'll read about people getting locked out of their identity .. like the folks today who lose their Bitcoin keys.
Your web server sucks for me ;)
Actually, it is even simpler than that. If you have the Inline::Perl5 module installed, then the only thing you need to do to load a Perl module, is to use the :from<Perl5> adverb in the -use- statement, e.g.:

use DBI:from<Perl5>;
I tend to agree, everyone knows how to ride a bike and learning to row without injuring yourself, even on a machine, takes time. I wonder what % of people with rowing machines at home, c2 or otherwise, are current/former rowers vs crossfit, regular gym goers, etc
Yeah, but privacy used to be a part of the mission, with the understanding that privacy was a good thing but not the only thing. It seems like over the years the focus has shifted to privacy being the ultimate goal, and every other aspect of the mission happens in the name of privacy. And there's no acceptance of the idea that some well-informed people are willing to make a decision to sacrifice some privacy in exchange for convenience or cost, anybody who considers sacrificing some of their own privacy is treated as a moron who needs to be protected from themselves.
Faster to program yes, massively so. Faster to execute, it depends on what I'm doing, but it's never a problem for me as my data is usually pretty small and quite messy. It doesn't feel slow at all, at least. And obviously if you're doing arrays you'll certainly not run faster in Python/R.

As for R/Python it's mostly familiarity with the notation (especially for python) and established popularity, with a large ecosystem as a consequence.

I mean, as a beginner in Python it just works (slowly). As a beginner in J, you cry... The interesting distinction is that Python/R APIs can be quite convoluted and the rug may be pulled from under you without warning, while in J you learn the primitives and you're off to the races. Also, J is much faster for its use case and avoids the need to write C in most cases where using it is relevant.
That was the very first thought that popped into my head.
Ah, yes, so I was. Sorry to sow the very confusion you're trying to obliterate.
There's tons of advanced chip manufacturing in the USA. There are fabs all over the USA for companies like Intel, Infineon, Texas Instruments, ON, NXP (Motorola). It's the country's fourth largest manufacturing export.

TSMC leveraged a huge gap in the market early on. Since most fabrication plants were owned by companies that also designed and sold chips, it was hard to get contracts for production volumes. This made it basically impossible to be a fab-less design company, like nVidia, because Intel/TI/etc might not produce your chips if they didn't have spare capacity.

With a foundry, that's not a concern.
Let's appreciate that this project try to give visibility to personal self-hosted blogs (not mediums, linkedins, substacks, dev.tos) and is using (I guess) good old RSS tech to get the articles.

I’m not sure that the capital markets are a good measurement device for censorship-resistant truth. The money supply is so distorted, specifically the huge amount of reserves held by a few banks and individuals, that most traders are making bets on those entity’s investment decisions (positive feedback) rather than price to value (negative feedback).
This won't ever get anywhere.

The public doesn't know about Diffie Hellman or Brian Acton or Mike Schroepfer or Alex Halderman and yet here we are.

What else do you need to know about Moxie Marlinspike or Matthew Hodgson and Amandine Le Pape beyond their technical blogs, opinion blogs and conference appearances and the products they put out there ? To decide what ? What does it change regarding their work being done in the open ?

If you suspect them of something there's nothing in the world that they could say or put out that would convince you they aren't... what ? Why is being secretive suspicious and concerning ? What are you suspecting ? You already know more about their name and what they do and think that people who worked on covid vaccines and that has a significant amount of influence and society.
For me, I made something that I wanted for myself. Originally it was just a script I used myself - I built the web service after, once I realised that this might be useful for others. It's B2C and transactional rather than SaaS, which is against the usual wisdom and but there's upside in that it is a more comfortable, less exigent business to be in.

It's not in my usual domain but still technically interesting - that's a large part of the reason I was motivated to work on it outside of the 9-5. Build it lean so that you don't need to spend too much time on it. Your product will look more focused to boot.
One big barrier to online voting is that you don't want people to be able to be forced to show their votes which makes any kind of verification immensely difficult (you have to accomodate people needing to show a fake verification) because otherwise you leave things open to voter intimidation and vote buying.

Another is that by going online you instantly open the attack surface up massively. Currently to steal an election you have to physically move a large number of people to a broad set of voting sites or send in a lot of forged mail votes. Those both require physically doing something in the US where an online system lets anyone in the world potentiall attack the system.
IMHO, accounting for politics is a vital, basic part of planning.

How people quietly perceive your planning, how your planning feeds into their hidden plans, how people could use your planning against you.

It's a delicate, dangerous territory that most shy away from exploring. Which, I think, makes a clear map about that territory all the more valuable.
This isn't the bluetooth, it's a known problem with the AirPods Pro. I used the regular AirPods (with no issues) for a year before getting AirPods Pro, which I then used for a couple months before the increasingly bad audio issues made them completely unusable. I ended up buying a new pair of the regular AirPods and, again, no issues.

I read somewhere that it was an early-batch problem and that it's been fixed in newer iterations of the Pro, but there's no way I'm going to spend money on them again just to find out. The AirPods Pro are the only Apple device I've ever been totally and completely disappointed with. The regular AirPods remain one of the most unambiguously-good Apple devices I've bought.
I created tools such as https://spamscanner.net and use ARC + ARF.
Yep part of the goal with Jel is to raise the bar on what kind of collaboration can be done beyond the "talk + screenshare" model.

If you imagine interacting with each other as you would in a video game, this can be a new category of meeting, with a rich set of archetypes. The screen sharing archetype can be one of many possibilities, albeit not one that is (to your point) particularly well suited since the existing tools do well enough with that use case. The hope is that the existing metaphors people are used to can just act as a bridge to enabling them to take more full advantage of the benefits of a fully spatial, mixed media 3D world.
It'd be fraud/abuse, and I'd expect it to be prosecuted, so nobody "gets" to opt out, but refusing to help many people because a handful could potentially abuse the system is not something I'm willing to do.
Agreed. On my iMac Pro, both AirPods and AirPods Pro had serious reliability issues. Occasionally during calls I would end up having skipping audio issues, and my bluetooth magic trackpad would also stutter when these issues were ongoing. Sometimes the bluetooth driver would seemingly crash, everything would reconnect, and it would be fine.

The workaround I discovered was that if I plugged in my bluetooth trackpad via USB during a call, these issues would basically never happen.

Not to mention all the other general issues with them failing to stay connected to my Mac, or failing to connect initially. These issues also happened on multiple MacBook Pros, including new top-of-the-line 16" models. Whereas I have basically zero problems with AirPods on my iPhone or AppleTV.

In short: the macOS bluetooth stack has some serious shortcomings that aren't present in iOS.
> One nice thing about newer C++ is that you can write safer(in some sense) functions.

But in practice you rarely find these in the codebase you inherit.
Disclaimer: I work at Backblaze.

> I always thought peer agreements are under NDA. Surprise to see they talk openly.

Both Backblaze and CloudFlare are very open about this. It is called the "Bandwidth Alliance", you can read about it at these two links:

https://www.backblaze.com/blog/backblaze-and-cloudflare-part...

https://www.cloudflare.com/bandwidth-alliance/backblaze/

For Backblaze, it's part of our business strategy to be open and honest with customers. That feels funny to type, but it's true. We have historically disclosed things that other companies have traditionally kept secret, like our internal drive failure rates. I don't know if this is surprising or not, but it has worked well financially for us. Meaning we explain what is going on, more potential customers hear about us, more customers trust us, our sales increase.

I'm actually curious why other businesses keep their operations so secret?
Jet fuel (which powers the turbine engines that Harbour Air uses) is actually quite similar to Diesel. Some turbines have diesel listed as an approved emergency fuel, particularly military aircraft.

You might be thinking of avgas which has lead in it, but turbine engines don't burn avgas.
This is on in memory data. So binary search would seem reasonable except that you can't do inserts, updates, or deletes efficiently in an ordered array. That inevitably leads to using a btree or trie structure.
In 2017 I got a second hand Cisco ASA just to play with the shadowbrokers tools. EXTRABACON was the codename for the SNMP exploit using a buffer overflow.

This was an interesting excercise because there were NO logs of this happening on the Cisco ASA, not even when ramping every loglevel to debug. Well only on the console port. Exception in readline() or something like it. Doing stuff for security monitoring in daily life this ehm was alarming, but not unexpected. Fixing “No logs” is often a challenge for blue teams.

Anyway it was alarming enough to find and read through the Common Criteria EAL4+ certification docs for the Cisco ASA only to find that SNMP was excluded from certification scope. I still have the idea in the back of my head to explore scope exclusions in other certification docs for other unfortunate exclusions.

Also the lack of mitigations like stack canaries, ASLR or others was quite surprising for a certified black box security device on the network perimeter.
Should probably be classified as a meta-breach. :)
Bluetooth is infuriatingly broken. Headphones work sometimes and not others. My car sometimes connects to my phone and other times not. Doing Bluetooth voice chat on discord with some games breaks game audio completely.

The most reliable Bluetooth I've found is a hardware device that pretends to be a USB sound card and connects to my headphones via Bluetooth. Anything with a full operating system seems like a disaster.
I can't put the article better than it puts itself. I'd recommend everyone read it top to bottom. tl;dr If everyone's playing tug of war, everyone has to spend all this effort pulling just to stay where we are.

What I'll add is how this seems to show up in HN discussions. A frequent trope here is an article about someone or some company doing something that pisses people off, then the comments debating whether it's the incentive-maker's fault and it's not wrong for people to maximize according to the incentives provided. The whole thing is a microcosm of this lack of trust.

It's like the prisoner's dilemma. What's lost isn't the decision to trust, it's the whole framing. In a perfect trust society, taking the compete option in a prisoner's dilemma would be seen as immoral. In a zero trust society, the whole choice reduces to analyzing the payoff matrix. That's what's lost. It's the change from a framing around 'cooperation is the moral action' towards a framing around payoff matrices.

I'd argue that on HN, the general sentiment is on the payoff matrix end of the spectrum.
When this update popped up, I seriously thought something was wrong since the new permission didn't make any sense. Disabled update across everywhere I use extension.
Valgrind helps a lot though, it usually solves my memory errors. (If that doesn't do it, then it's either just a logic bug, or you have a really strange bug in the first place!) The main issue people have with it is that its terminal interface is almost always unusable (you get thousands of lines of gibberish text), and there aren't many good Valgrind GUI frontends available. Thankfully CLion has an integrated valgrind inspector that really helps a lot.
Kudos to the team over there for being as transparent about what happened and where they were not following best practices - I am pretty sure most companies would not publicly admit this:

we had secrets sprinkled in source control, in plain text in build systems and available through settings screens in the application.
That's fine, but then you have to assume the same of the CIA and 101 other countries/agencies. So you have to design and build every part of all your systems nationally down to the copper wire pretty much and only after you've vetted all the people involved.

Just so your 5G system can't be turned off?
A true classic that is just as relevant today as ever.

The source is openly accessible, openly developed, and you can fork it if you don’t like it. It’s definitely open source.
Haha thanks! (OP here) I'm using a combination of the Twitter API, RSS, and Puppeteer to put the data together. RSS is nice but not always complete, and some blogs don't have it :)

Glad you enjoy it, and yes, the goal is to make it easier to find blogs from individuals. I don't reject sites hosted on 3rd party platforms, but I do encourage people to post their own domain name when possible.

>A frequent refrain I encountered when trying to talk with friends/family was that I had “first-world” problems that weren’t worth talking about. Ugh.

Isn't this somewhat true from their perspective? They have just as much difficulty relating the other way
It's fine to take issue with charged language like the word "stolen", which can be interpreted in different ways; maybe you interpret that as "I won the vote count but the votes were changed", but it could also be reasonably interpreted as "I lost the vote count but I'm concerned people were influenced to vote that way through nefarious means".

I think there is a reasonable distinction between that statement and the specific claims of fraud we have been seeing for the last few months.

I'd worry that their kids wouldn't be up to date on their vaccines. You really don't want measles.

It's a low risk, obviously, especially if you are up to date. But as much as I like hippy vegans (not being sarcastic!) I would still worry they are walking around as potential measles incubators. If they have religious objections to wearing a piece of cloth over their face they probably aren't too excited about vaccines.

It's way down the list of things to worry about nowadays, obviously. But still.

Healthcare spending is something of a mystery. Two examples: there's a huge epidemic of allergies happening under our noses, and no one seems to be paying it any mind. Coronaviruses were known to be problematic years ago, and no one bothered to invest in prevention.

I guess there aren't enough researches (or money) to go around...
It's not clear to me that any of this is a good idea.

For example:

> Just to be clear: this is not about just following your child around, cleaning up after them. That would be a failure to teach them responsibility, and yes, that teaches entitlement. This is about seeing yourself as a willing helper, the extra support that our children need to practice or to be willing to do it themselves.

It's not clear to me that just changing the way we see ourselves will actually achieve anything. Even if we see ourselves as "willing helpers", the child might take that to reinforce their view that everyone should be helping them willingly.

I love thoughtful mini-essays, and this is one of those. I just think that in this case the author reaches the wrong conclusions.
Offtopic: The site uses payhip for payments, which I thought it was actually Gumroad as it uses the same loading spinner. Is there an affiliation between Gumroad and Payhip? Did they just copy Gumroad's checkout?
I'm not OP but I suspect I'm in their target demographic. Orangetheory Fitness doesn't use the Concept2 and no one cares. I've never once heard anyone at Orangetheory complain that the machine wasn't a Concept2.

I don't think the former rowers in this thread complaining about the machine are at all reflective of the public at large.
Yea, 10 minutes & a text message would suffice, IMO...
We've never remotely had anything akin to socialism in the US. The USSR, China, Cuba, Venezuela, yes, absolutely. But neither socialism nor communism were ever used here in the US.
Arguably that's more like a four-wheel scooter. I generally draw the line at Smarts (although I think the new Twingo uses the same platform as Forfour).
Since you've got everything in a git repo it would be really easy to diff/fork/merge other folks' knowledge bases.

Probably not useful to you personally since there aren't forks out there yet, but it's cool to see you've got all the infrastructure in place for some kind of "mind meld" feature.
